BacktoBack Relative Frequency Histograms When using histograms to compare two data sets
Chapter 2, Problem 19(choose chapter or problem)
BacktoBack Relative Frequency Histograms When using histograms to compare two data sets, it is sometimes difficult to make comparisons by looking back and forth between the two histograms. A backtoback relative frequency histogram has a format that makes the comparison much easier. Instead of frequencies, we should use relative frequencies (percentages or proportions) so that the comparisons are not difficult when there are different sample sizes. Use the relative frequency distributions of the ages of Oscarwinning actresses and actors from Exercise 15 in Section 22, and complete the backtoback relative frequency histograms shown below. Then use the result to compare the two data sets.
